As single quotes cannot be escaped with a backslash and double quotes like to evaluate, looks like double quotes is a best bet in my case.
Still investigating if we use sed double quoted "" escape normal character such as number 1 as \1 inside the sed, will it replace the \ and 1 as well, I know it \$ evaluates to $?

Bad example of \1 as it is back reference , let me use \A
echo "abc-A \ cde fg A \ hi" | sed -e "s/\A/ /g"
abc- \ cde fg \ hi
does not replace '\'
How can I use sed to replace a ctrl character such as 'new line' (\0a) to something else? Or any other good command can do this job?
Thanks,
